The answer is most likely the second choice. All answer choices could be possible, but in light of the others the second choice is far too specific, and there is no information in the prompt to even indicate that as a plausible answer choice.
Answer:
Calcium ion is necessary to activate the binding sites on the actin molecules.
The molecule ATP is required each time the mysoin head detached from one sites and reattached.
Explanation:
Depolarization of sarcomere recticulum causes it to release calcium ion. Calcium ion then bind to troponin and reconfigure the complex exposing the binding sites to myosin head on the actin filaments.
The cellular importance of motor is to deliver ATP dependent force impulse to actin molecule.
When ATP molecule bind, the mysoin head detaches from old binding sites of actin, reattaches to new actin monomer. When ATP is hydrolysed, it changes conformation causing actin to slide in respect to myosin.
Answer:
D
Explanation:
Not sure but the sentence is super understamdable
I am pretty sure that it is in the prophase
Oxygen has eight electrons . the first two electrons will go in the n=1 level . the n= 2 level can hold up to eight electrons so the remaining six electrons will go in the n=2 level . the election arrangement of Oxygen is ( 2, 6)
